摘要: 对地震勘探中反演声阻抗的一维反问题提出了一种算法。先将反问题进行差分离散化为某一非线性方程组,然后对这一非线性方程组进行Newton线性化,再采用LMS迭代。最后给出一模拟算例,验证了本文算法的有效性。

Abstract: In this paper a new algorithm for 1-D inverse problem of wave equations in seismic exploration is given. The inverse problem is changed to be a system of nonlinear equations by the method of difference. The system is linearized by Newton's method, then it is solved iteratively by LMS's method.
